ABSTRACT

A positioning structure enabling blister-on-card packages to stand vertically in a packing box to facilitate display of commodities in the packages is provided. The positioning structure includes a pair of positioning plates symmetrically attached to two opposite inner wall surfaces of the packing box. Each of the positioning plates is provided at one side with two horizontal rows of equally spaced projections, such that a vertical straight insertion space is formed between any two adjacent pairs of projections in the two rows. Blister-on-card packages are positioned in the packing box with two lateral edges of the cards forming a back of the packages received in two insertion spaces symmetrically provided on the two positioning plates, allowing the blister-on-card packages to stably and upright stand in the packing box for display.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a positioning structure for holding blister-on-card packages in a packing box, and more particularly to a positioning structure that enables blister-on-card packages to vertically and orderly stand in the packing box for display.

[0002] Currently, there are a lot of commodities being packaged in a shaped plastic shell that is then fixed to a card back. This type of package is commercially referred to as the blister-on-card package. FIG. 1 shows an example of a commodity packaged in this manner. To simplify the description herein, reference numeral 20 will be used to denote both the blister-on-card package and the commodity packaged therein. As shown, the package for the commodity 20 includes a card 21 that forms a back of the package and a shaped plastic shell or a blister 23 that defines a space 22 and forms a front of the package. The card 21 is locally provided at a front surface with heat-meltable clear glue corresponding to a profile of the blister 23. When the blister 23 is covered onto the front surface of the card 21 to enclose the commodity 20 in the space 22, the glue is heated to bond the blister 23 to the card 21 and protectively seal the commodity 20 in the space 22. Patterns and/or words may be printed on the card 21 to describe the commodity 20 and attract consumers. The blister-on-card package makes the commodity 20 looked more valuable and is one of the most popular packaging manners.

[0003] The blister-on-card package 20 itself is not able to stand vertically. It is a common practice to provide at a top of the card 21 with a small hole 24 through which a bar-like hanger is extended to hang the whole card package on the hanger for display purpose. An alternative way for displaying the blister-on-card packaged commodities 20 is shown in FIG. 1. That is, to sequentially and vertically position the blister-on-card packaged commodities 20 in a packing box 10. To do so, a positioning support 11 bent into a U-shaped cross section is disposed in the packing box 10. The positioning support 11 is formed of equally spaced slots 12, each of which extends from a bottom of the packing box 10 upward to two opposite walls of the packing box 10. Each slot 12 is adapted to receive three lower outer areas of a blister-on-card package 20 therein and thereby hold the package 20 in a vertical position in the packing box 10.

[0004] A first drawback of this type of U-shaped positioning support 11 is that it must be differently produced to meet blister-on-card packages of different widths. That is, a number of differently sized molds must be designed to produce differently sized positioning supports 11 for holding blister-on-card packages 20 of different widths. Another drawback of the U-shaped positioning support 11 is that it is formed through vacuum molding and hollow walls 13 at two sides of each slot 12 tend to deform because they have small thickness and therefore low structural strength that is not sufficient to stably keep the blister-on-card packages 20 in an upright position in the packing box 10.

SUMMARY OF THE INVENTION

[0005] It is therefore a primary object of the present invention to provide a positioning structure that has sufficient structural strength to hold blister-on-card packaged commodities in an upright position in a packing box.

[0006] Another object of the present invention is to provide a positioning structure that is applicable to vertically support blister-on-card packages of various widths to simplify the packaging operation.

[0007] The positioning structure of the present invention mainly includes a pair of positioning plates symmetrically attached to two opposite inner wall surfaces of the packing box. Each of the positioning plates is provided at one side with two horizontal rows of equally spaced projections, such that a vertical straight insertion space is formed between any two adjacent pairs of projections in the two rows. The projections and the insertion spaces are symmetrically provided at the two opposite inner wall surfaces of the packing box. Each blister-on-card package is vertically positioned in the packing box with two lateral edges of the back card of the package received in a pair of insertion spaces symmetrically provided on the two positioning plates, allowing the commodity in the package to stably stand upright in the packing box for display.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Please refer to FIGS. 2 and 3. A positioning structure provided by the present invention to enable blister-on-card packaged commodities 20 to stand vertically in a packing box 10 includes a pair of thin flat positioning plates 30 symmetrically attached to two opposite inner wall surfaces of the packing box 10. Each of the positioning plates 30 is provided at one surface at predetermined positions with two horizontal rows of equally spaced projections 31. Each projection 31 in an upper row of the two horizontal rows corresponds to a projection 31 in a lower row to provide multiple pairs of corresponding projections 31. The two projections 31 in one pair are located in the same vertical line, such that a vertical straight insertion space 32 is formed between any two adjacent pairs of corresponding projections 31. The insertion space 32 each is wide enough to receive an edge 25 of the back card 21. By inserting two lateral edges 25 of the back card 21 of the blister-on-card package 20 into a pair two opposite insertion spaces 32, the commodity 20 could vertically stand in the packing box 10.

[0014] The two positioning plates 30 in one pair attached to the walls of the packing box 10 are identical with each other. Therefore, the insertion spaces 32 formed between any two adjacent pairs of projections 31 on the two positioning plates 30 have the same width. This advantageously enables convenient production of the positioning plates 30 and easy generation of insertion spaces 32 of regular width on the two positioning plates 30.

[0015] The positioning plates 30 are designed to have high structural strength, so that the projections 31 thereon have excellent supporting strength to support the blister-on-card packages 20 and the commodities therein in a vertical position without the risk of becoming collapsed. That is, the pair of positioning plates 30 in the packing box 10 ensures that the commodities 20 stably and upright stand in the packing box 10. As can be seen in FIG. 3, each of the projections 31 defines at a rear side a hollow hole 33. This design enables production of the positioning plate 30 with reduced material and prevents the projections 31 from easily becoming deformed.

[0016] The pair of positioning plates 30 may be cut to a desired length depending on actual need and then be attached to the inner wall surfaces of the packing box 10 by means of, for example, an adhesive agent. On the other hand, more than one positioning plate 30 can be connected to provide an extended positioning plate as necessary.

[0017] The paired positioning plates 30 of the present invention are characterized in that they could be applied to hold differently sized blister-on-card packages 20. This is because the positioning plates 30 hold the packages 20 only at the two lateral edges 25 of the back cards 21. In the event the commodities 20 to be supported in the packing box 10 have a large height or a high center of gravity, it is possible to attach the pair of positioning plates 30 to the two opposite inner wall surfaces of the packing box 10 at higher positions to enable stable support of the commodities 20 in the packing box 10.

[0018] With the positioning plates 30 of the present invention, blister-on-card packaged commodities 20 could be sequentially vertically positioned in the packing box 10 in a stable manner for display. And, general customers could easily view the commodities 20 and move or replace the whole blister-on-card package of the commodity 20 out of or into the packing box 10.

[0019] The positioning plates 30 of the present invention have simple structure while they are capable of firmly holding the blister-on-card packages 20 in an upright and stable position. The application of the positioning plates 30 of the present invention in holding blister-on-card packages 20 of various widths is almost unlimited so long as the positioning plates 30 are symmetrically attached to two opposite inner wall surfaces of the packing box 10. 

What is claimed is:
 1. A positioning structure enabling blister-on-card packages to stand vertically in a packing box, comprising a pair of positioning plates symmetrically attached to two opposite inner wall surfaces of said packing box; each of said positioning plates being provided at one side at predetermined positions with two horizontal rows of equally spaced projections, each of said projections in an upper row of said two horizontal rows corresponding to one said projection in a lower row to provide multiple pairs of corresponding projections on each said positioning plate, said two corresponding projections in one pair being located in the same vertical line, such that a vertical straight insertion space is formed between any two adjacent pairs of said corresponding projections; and each of said insertion spaces being wide enough to receive an edge of a card that is usually used together with a shaped plastic shell or blister to package a commodity, so that each said commodity packaged in blister on card could vertically stand in said packing box with two lateral edges of said card received in a pair of two opposite insertion spaces provided on said pair of positioning plates attached to two opposite wall surfaces of said packing box.
